Mobility-enhanced positioning in ad hoc networks

This paper discusses and investigates the effects of mobility on positioning of wireless ad hoc networks. We present a mobility-enhanced ad hoc positioning (MAP) scheme, where we leverage on the mobility of nodes within network. The scheme uses the hop counts information from fixed reference nodes to perform positioning and improves accuracy by using mobile nodes to "bridge" gaps within neighborhoods where accurate information was not available. Simulation shows that using mobility does improve the performance of such "hop count"-based positioning schemes.
